128916-30-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 128916-30-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,9,1 and 6 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 128916-30:
(8*1)+(7*2)+(6*8)+(5*9)+(4*1)+(3*6)+(2*3)+(1*0)=143
143 % 10 = 3
So 128916-30-3 is a valid CAS Registry Number.

Nickel-catalyzed oxidative dehydrogenative coupling of alkane with thiol for C(sp3)-S bond formation

Liu, Shengping,Jin, Shengnan,Wang, Hao,Qi, Zaojuan,Hu, Xiaoxue,Qian, Bo,Huang, Hanmin

supporting information, (2021/03/15)

A nickel-catalyzed oxidative dehydrogenative coupling reaction of alkane with thiol for the construction of C(sp3)-S bond has been established, affording more than 50 alkyl thioethers. Notably, pharmaceutical and agrochemicals, such as Provigil, Chlorbenside and Pyridaben, were readily synthesized by this approach. The sterically hindered ligand BC and disulfide which was formed in situ oxidation of thiol, efficiently avoiding nickel-catalyst poisoning. A set of mechanistic experiments disclose both Ni-catalyzed and Ni-free HAA processes.

A mild method for the cleavage of the 4-picolyloxy group with magnesium under neutral conditions

Zhu, Jianwei,Miao, Wenjun,Bao, Lingling,Ji, Tao,Tang, Guo,Xu, Pengxiang,Zhao, Yufen

supporting information; experimental part, p. 142 - 144 (2012/02/04)

A mild and efficient method for the selective hydrolysis of 4-picolyl esters with magnesium in methanol or water in the presence of other esters and sensitive protecting groups is described. 4-Picolyl aryl ethers and thioethers are also smoothly deprotected to give the corresponding phenols and thiophenols.
